In the following excerpt, Dallas -- the captain of the spaceship -- asks the crew if they have any last words before he jettisons Kane's dead body into space. A cut-away on screens divides a shot of Dallas and the crew. Before the insert, the crew is in focus and Dallas remains blurry in the foreground. After the insert, the focus has shifted to Dallas who is now in control, as nobody's willing to say anything. So here, a cut-away is inserted in a shot to detract attention from a necessary shift in focus.
